This restaurant seems to have undergone a recent name change from Kyozon to L'Atelier D'Argentine (although the credit card receipt still shows Kyozon). This was easily one of the worst dining experiences of my life. Highlights include the following: 1. Slow, inattentive service with very few customers there. 2. Inedible food, bearing little resemblance to anything of any quality from Argentina. And 3. Dirty tableware. The bottle of Malbec was good, if that was any consolation. Easily amongst my five worst dining experiences.
